Definitions

  • the invention relates to a separator with a vertical axis of rotation according to the preamble of claim 1.
  • Such a separator is known from DE 10 2004 038 613 Al. As described in this document, it may come in a use of separators for the sterilization of milk u.U. too short-term deterioration of the sterilization efficiency due to pressure increases in the inlet, the z. B. caused by partial discharges, Tankum- circuits or by an increased air content in the product. Another problem is the transport (shaft run) of germs to the peeling disk.
  • connecting holes to an annulus which is formed above the free end of the inlet pipe in the manifold, are provided that extend the connection holes between a preferably conical inlet space and the annulus , and that the outlet openings from the inlet space in the inlet bores of the distributor and the connecting bores to the annular space is assigned in each case a rib.
  • the ribbed body is easy to assemble.
  • the inlet pressure can be reduced and the feed rate increased. This results in a gentle re product feed in the distributor.
  • the risk of deposits forming in the inlet area is reduced.
  • one or more of the axis of rotation is aligned, which means a strong acceleration of the material to be centrifuged in the circumferential direction. But it is also conceivable to make them relative to the respective radial, for example, between 1 ° and 80 °.
  • the ribs may be straight, but also curved. It is also conceivable a blade-like design with curvatures in all directions, as long as an acceleration effect in the circumferential direction is given.
  • FIG. 1 shows a simplified section through a centrifugal drum of a separator according to the invention
  • Fig. 3, 4 are each perspective views of rib bodies.
  • FIG. 1 shows a simplified representation of a partial region of a centrifugal drum 1 of a continuously operable separator rotatable about a rotation axis D, in which a plate package 2 of a multiplicity of plates 3 is arranged concentrically to the machine axis or axis of rotation D.
  • the centrifugal drum is here twice conically formed inside.
  • the plates 3 have a conical shape, are stacked axially one above the other and by means of spacers, not shown here (tabs and the like.) Distance from each other.
  • the plate package 2 is held on a distributor shaft 4 of a distributor 5, which is provided on its outer periphery with radially outwardly projecting webs (here not visible), which engage on the inner circumference of the plate 3 in this.
  • the plate package 2 has riser channels 6, which consist of directly superimposed holes in the plates 3 and extend over the entire height of the plate package 2.
  • An inlet pipe 7 lying concentrically to the machine axis makes it possible to feed a centrifuged material from above into the centrifugal drum 1 and through the distributor shaft 4 and below the plate package 2 in the distributor 5 into the plate package 2, for example in the region of the riser channel 6 or on another place.
  • Peeling discs (not shown here) and solid discharge openings 10 are derived from the centrifugal drum 1.
  • the solids discharge openings 10 are preceded by a piston slide 11, which is vertically movable and with which the solids discharge openings can be opened and closed.
  • a product supplied through the inlet pipe 7 first enters from the inlet pipe 7 into an inlet chamber 12 in the center of the distributor shaft 4, the free lower outlet of the inlet pipe 7 extending below the upper edge of the inlet chamber 12.
  • the distribution channels 8 begin in the peripheral wall 13 of the inlet pipe.
  • the feed chamber 12 is designed according to FIG. 1 such that a ribbed body 14 with one or preferably a plurality of ribs 15 can be inserted into it.
  • the ribbed bodies 14 are rotatably connected to the centrifugal drum, preferably with the distributor 4, connected.
  • FIGS. 3 and 4 two suitable ribbed bodies 14 are shown in FIGS. 3 and 4.
  • the illustrated ribbed bodies 14 each have a base portion 16.
  • This base portion 16 is preferably formed as a circumferentially closed ring portion (Fig. 1 ', Fig. T).
  • the annular base portions 16 are flat, so that they extend in the installed state perpendicular to the axis of rotation D, according to Fig.l it extends vertically, according to Fig. 2, the base portion 16, however, is conical.
  • the base portion 16 is rotatably connected respectively to the rotating system, in particular to the distributor 4.
  • the shape of the base portion 16 preferably corresponds in each case to the shape of the distributor 4 in a corresponding contact or support area.
  • the ribs 15 project vertically vertically and when installed, they are also vertically aligned.
  • the base sections 16 of the exemplary embodiments of FIGS. 3 and 4 are preferably oriented vertically downwards so that the ribs 15 project vertically upwards into the inlet space 12.
  • the ribs 15 of the embodiments are formed integrally with the base portion 16 and project from one axial side thereof vertically.
  • the ribs 15 are formed circumferentially distributed on the base body 16. The radial length of the ribs
  • the ribs 15 preferably corresponds at least to the vertical height of the inlet openings 17 in the distributor channels 8.
  • the ribs 15 are aligned according to a variant radially to the axis of rotation D (Fig. 3, Fig. 4). But you can also - see Fig. 2 - be aligned at an angle to the radial direction.
  • the ribbed body 14 is inserted or installed in the annular space 12.
  • a bore-like inlet opening 17 from the inlet chamber 12 into the inlet bores or channels 8 is formed or arranged directly behind each of the ribs 15 and radially outside the ribs.
  • the ribs are located radially inward to the inlet openings 17th
  • the rib body 14 as a whole or as a single element in the assembly of the centrifugal drum is easily settable in the inlet chamber 12, where it is fixed in rotation against the distributor 4, which is e.g. by fastening means such as screws, bayonet-like, by shitting or the like. Can be done.
  • the inlet chamber 12 is designed such that it adjusts a pressure increase in relation to a configuration without ribbed body 14 in operation.
  • the inlet pipe 7 has a disk section 18 (a "hydro disk") which, according to FIG. 1, is advantageously - but not necessarily - formed at the vertically lower end of the inlet pipe 7, where it extends from the inlet pipe 1 perpendicular to the axis of rotation D or perpendicular to the axial direction of the inlet pipe 7 outwardly to the inner circumferential wall of the distributor 4.
  • the remaining gap is preferably less than 10 mm, more preferably less than 7 mm radially inwardly projecting lug 24 at the upper end of the distributor forms an additional closure in operation radially upwards.
  • the inlet pressure can be reduced by installing the ribbed body, eg at 80000 l / h feed rate by 0.5 bar.
  • the feed rate can be increased accordingly.
